Lawrence Livermore National Laboratory scientists and collaborators are using machine learning to address two key barriers to industrialization of two-photon lithography (TPL): monitoring of part quality during printing and determining the right light dosage for a given material. The team developed a machine learning algorithm trained on thousands of video images of TPL builds to identify the optimal parameters for settings such as exposure and laser intensity and to automatically detect part quality at high accuracy.
Two-photon lithography (TPL)—a widely used 3-D nanoprinting technique that uses laser light to create 3-D objects—has shown promise in research applications but has yet to achieve widespread industry acceptance due to limitations on large-scale part production and time-in...

Engineers create centimeter-sized robots capable of more than ever before. Origami principles can unlock the potential of the smallest robots, enhancing speed, agility and control in machines no more than a centimeter in size.
University of Michigan researchers have demonstrated that behavioral rules underpinning the Japanese art of folding can expand the capabilities of these machines, creating potential for greater use in fields as diverse as medical equipment and infrastructure sensing.

Study of bacterium links biology, materials science, and electrical engineering. When the Shewanella oneidensis bacterium “breathes” in certain metal and sulfur compounds anaerobically, it produces materials that could be used to enhance electronics, electrochemical energy storage, and drug-delivery devices.
The ability of this bacterium to produce molybdenum disulfide – a material that is able to transfer electrons easily, like graphene – is the focus of research published in Biointerphases by a team of engineers from Rensselaer Polytechnic Institute.
“This has some serious potential if we can understand this process and control aspects of how the bacteria are making these and other materials,” said Shayla Sawyer, an associate professor of electrical, computer, and systems ...
Officials say quantum technology could become the basis for a more secure internet architecture
US officials and scientists have begun laying the groundwork for a more secure “virtually unhackable” internet based on quantum computing technology.
At a presentation Thursday, Department of Energy (DOE) officials issued a report that lays out a blueprint strategy for the development of a national quantum internet, using laws of quantum mechanics to transmit information more securely than on existing networks. The agency is working with universities and industry researchers on the engineering for the initiative with the aim of creating a prototype within a decade.
In February, scientists from DOE’s Argonne National Laboratory and the University of Chicago created a 52-mile (83-kilomete...
